I'm looking for a 10/12" sub that can handle around 500-600W RMS. I listen mostly to techno and only plan to use a single sub for weight/space savings. My amp is the alpine MRD-M500. I've done a little research but I've been out of the game for a while and dont really know whats new. I'd really like a 10w7 but the price is still up there. Are elemental designs any good? Oh and I prefer SQ over SPL any day.
